Abstract

The invention relates to a rolling element cage (10, 60) for a rolling bearing, which cage (10, 60) has a first side part (12, 62) and a second side part (14, 64) for axially guiding rolling elements and in which cage the two side parts (12, 14, 62, 64) are connected at an axial distance from one another by connecting bolts (16, 66). To achieve the object of the invention, the connecting bolts (16, 66) have a first threaded section (18, 68) comprising a first outer thread (34) on one axial end and a second threaded section (20, 70) comprising a second outer thread (35) on their second axial end, each threaded section (18, 20; 68, 70) of the connecting bolts (16, 66) is screwed into an associated threaded hole (30, 32; 74, 76) in the first side part (12, 62) and in the second side part (14, 64), the holes having an inner thread (37, 39), and at least one end face (108, 110) of each connecting bolt (16, 66) has an engagement geometry (114) allowing at least some of its regions to interlockingly receive a tool for screwing the connecting bolts (16, 86) into the threaded holes (30, 32: 74, 76) of the two side parts (12, 14, 62, 64).
